The practice you do in yoga class is not, strictly speaking, yoga practice. The reason for this that in a class, although you are undoubtedly “doing” and, hopefully, learning, you are subordinate to the teacher. The directing intelligence comes from him, and you follow to the best of your ability. At home, on the other hand, it is your own intelligence that is the master, and the progress that you make is yours and will be maintained... It comes from you, and it’s effect profound. This is not Yoga by the body for the body, but Yoga by the body for the mind, for the intelligence.

— BKS Iyengar, Light on Life, p. 166-167.
